Since MCP servers communicate over stdio, debugging can be challenging. We recommend using theMCP Inspector:

{ "name": "execute_command", "arguments": { "command": "git status" } }

{ "content": [ { "type": "text", "text": "On branch main\nNothing to commit, working tree clean" } ] }

{ "content": [ { "type": "text", "text": "Command execution failed: Command not allowed" } ], "isError": true }

The server provides detailed error messages for various scenarios:

{ "code": "InvalidParams", "message": "Command not allowed: [command]. Allowed commands: git, ls, mkdir, cd, npm, npx, python" }

{ "content": [ { "type": "text", "text": "Command execution failed: [error message]" } ], "isError": true }
